COURSE OVERVIEW:

Zonal isolation is the most critical requirement for the environmental and operational safety of a well, yet it remains one of the most difficult parameters to verify objectively. This course focuses on the rigorous quality assurance (QA) and quality control (QC) procedures necessary to ensure that a cement job meets its design objectives. It bridges the gap between the laboratory design of cement slurries and the field execution of the cementing operation, emphasizing that a successful job is the result of meticulous planning and real-time monitoring.

The scope of this training includes the evaluation of cement bond quality using modern logging technologies and pressure testing methods. Participants will learn how to interpret complex data from Cement Bond Logs (CBL), Variable Density Logs (VDL), and advanced ultrasonic imaging tools. The course provides a critical look at the factors that lead to poor bonding, such as micro-annuli, gas channeling, and contaminated cement, and offers technical solutions for verifying isolation in high-deviation and horizontal wells.

Coverage also delves into the regulatory requirements for barrier verification and the documentation needed for compliance. Students will explore the latest innovations in "smart cement" and real-time sensor technology that allow for continuous monitoring of the cement sheath throughout the well's life. By the end of this course, specialists will be able to confidently sign off on the integrity of a cement job or recommend the necessary remedial actions to correct isolation deficiencies before the well is put into production.

COURSE OBJECTIVES:

After completion of this course, the participants will be able to:

• Define the criteria for successful zonal isolation and barrier integrity.
• Implement a comprehensive QA/QC program for cementing operations.
• Verify laboratory test results against field-mixed slurry properties.
• Monitor real-time pumping data to identify displacement efficiency.
• Interpret Cement Bond Logs (CBL) and Variable Density Logs (VDL).
• Use ultrasonic imaging tools to distinguish between cement and fluids.
• Identify the presence of a micro-annulus and determine its impact.
• Evaluate the quality of cement in unconventional and HPHT wells.
• Perform and interpret dry and wet casing integrity tests.
• Utilize temperature and noise logs for leak detection and verification.
• Assess the risks associated with gas migration during cement setting.
• Coordinate with service providers to optimize logging tool selection.
• Document cement verification results for regulatory and corporate audits.

TARGET AUDIENCE:

Well Integrity Engineers, Drilling Supervisors, Cementing Specialists, Petrophysicists, and Regulatory Compliance Officers.

TRAINING COURSE METHODOLOGY:

A highly interactive combination of lectures, discussion sessions, and case studies will be employed to maximise the transfer of information, knowledge, and experience. The course will be intensive, practical, and highly interactive. The sessions will start by raising the most relevant questions and motivating everybody to find the right answers. The attendants will also be encouraged to raise more of their questions and to share in developing the right answers using their analysis and experience. There will also be some indoor experiential activities to enhance the learning experience. Course material will be provided in PowerPoint, with necessary animations, learning videos, and general discussions.

The course participants shall be evaluated before, during, and at the end of the course.

COURSE CERTIFICATE:

National Consultant Centre for Training LLC (NCC) will issue an Attendance Certificate to all participants completing a minimum of 80% of the total attendance time requirement.
